........My late partner was an experienced and well loved teacher at a major private school. She had one student observed over about three years who was a 'problematic" performer. ADHD was mentioned. His parents organised flying lessons for this brat. By chance I observed him at flying school a few times. He was not a diligent student pilot either - attitude problems including laziness and attention to detail.
He now flies for Qantas. Work that one out.
